Hidden in the fine print of President Trump’s latest budget proposal is a detail that could directly impact 9/11 first responders: The reorganization of the federal agency that oversees their health treatment and monitoring.

Currently, the World Trade Center Health Program is housed within the National Institute for Occupational Safety and Health. That agency, in turn, is under the umbrella of the Centers for Disease Control.

Under the 2019 fiscal year budget for NIOSH put forth by the White House, that agency will be carved out of the CDC and placed within the National Institute of Health.

The WTC Health Program will remain behind — within the CDC.

Although it would appear on paper to be a simple rearrangement, lawmakers and 9/11 advocates say the impact would be dreadful for the more than 83,000 responders and survivors who rely on the WTC Health Program to receive treatments, medications and monitoring for injuries and illnesses caused by toxins at Ground Zero and other 9/11 sites.
